23.4除以5.2乘以3.2

(3.8÷5.2)×23.4=64

23.4/5.2*3.2 =9/2*3.2 =(10-1)*1.6 =16-1.6 =14.4

解:原式=23.4x5.2x3.2=389.376. 答:答案是389.376.

5/23x(3/4+2/5)÷75% =5/23x23/20÷3/4 =1/4÷3/4 =1/3

25分之23除以(4分之3+5分之2) =23/25÷23/20 =23/25×20/23 =4/5

=23×(4×5) =23×20 =460

25分之23除以(4分之3+5分之2) =23/25÷(15/20+8/20) =23/25÷23/20 =23/25*20/23 =4/5
